A witness who was called to support defense claims that actress Lana Clarkson was depressed before her death at Phil Spector's mansion was accused by prosecutors Tuesday of saying the record producer should "fry" for killing her.

The Great Wall of China, Greece's Acropolis and Peru's Machu Picchu were leading contenders to be named among the new seven wonders of the world in a global poll whose results were to be announced Saturday.

Lana Clarkson was a depressed, 40-year-old, out-of-work actress fighting health problems and "at the end of her rope," according to a forensic expert who testified Wednesday that she was a candidate for suicide when she went to Phil Spector's mansion and wound up dead.

The Great Wall, the Colosseum and Machu Picchu are among the leading contenders to be the new seven wonders of the world as a massive poll enters its final month with votes already cast by more than 50 million people, organizers say.

After five weeks of dramatic personal stories about Phil Spector and the B-movie actress shot to death in his home, prosecutors are shifting their focus today to science and the critical forensic evidence.
